Creating Benefits and Saving Costs

The EPCL can be deployed to provide field-scale proof-of-concept for novel processes of biological remediation and augmentation and for performance-related auditing of wastewater treatment facilities. Design of novel treatment technologies and the re-engineering of existing unit processes can benefit from the vastly improved data banks on plant input characteristics now retrievable with the EPCL. There is substantial scope for improving
the reliability with which wastewater treatment processes achieve compliance, for minimizing their day-to-day consumption of energy, and for preventing and limiting pollution from faults, failures and accidents — occurring unexpectedly, as they do, in real time. Above all, there is much scope for deferring plant capacity expansion through optimizing performance of existing facilities and thereby avoiding costly re-building of new infrastructure. The Danfoss company understands this and has commissioned publication of the book by Ingildsen and Olsson "Get More Out of Your Wastewater Treatment Plant". There is a growing awareness of the significant benefits to be created and costs to be saved through facilities such as the EPCL. Our own research, following careful interpretation of HVHQ data from the EPCL (through a model), indicates substantial savings in annual operating costs to be gained, for example, from installing a mixer to control vertical resuspension and settling of biological flocs in the bioreactor of an Orbal activated sludge process.
